The three Black Knights is not an easy trio to reunite! I can well understand your efforts with them. Same with your triple date JLC duo!
And the Breguet Type XX? Wow! What a piece! Even its cardboard case is so charming!! And as you well say... best thing about these wonderful watches is that they are connected with nice stories and people behind.
Keep enjoying and loving them so much my friend. Have a nice week ahead! Cheers! Abel
